Lucas Rocks, Jenolan Caves, New South Wales.Very common species on rock outcrops, coast and mountains. Hard to associate this with the South African succulent Crassulas, and in fact species of this group were once placed in a separate genus
Tillaea. There may be arguments for reviving this classification. For that matter, see
www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=1...But [added later] it seems there is now strong cladistic evidence for including
Tillaea in
Crassula. See
